Patent DE-3539848-A1 (DE)
Title: Series controller
Inventor: KETTSCHAU HANS-JUERGEN DIPL IN
IPC: G05F1/575
Filed: 1985-11-09
Abstract: The application relates to a series controller having a controllable resistor in a series branch, with a series circuit of an ohmic resistance and a Zener diode in a shunt branch, the breakdown voltage of the Zener diode being used for controlling the controllable resistor in the series branch. If the controller is not transferring any power to a load, the power dissipation in the controller is avoided by the fact that a controllable switch is inserted between the ohmic resistance and the Zener diode which switch interrupts the connection between the ohmic resistance and the Zener diode when no load current is flowing through the controllable resistance, and that the contact gap of the controllable switch is bridged by a capacitor.

Title: Method and device for locating buried persons with the aid of correlative methods
Inventor: BOLTE OTTOGERD
IPC: A63B29/02
Filed: 1986-06-18
Abstract: A method is designed in such a manner that, due to the further development of a method known per se, by means of which unknown water leakages on lines run in the ground are located, buried persons can now be reliably traced. In this method, at least two geophones G1, G2, G3 are used for simultaneously picking up knocking noises, the noises being transmitted to a correlator via a cable or radio. From similarities of the noises, signal transit time differences are calculated in the correlator in accordance with the number of geophones G1, G2, G3, from which differences the position of the buried person K is obtained. Before this, however, mean velocities of sound propagation in the measuring area are measured with the aid of separate sound generators by means of which correction factors can be calculated for the velocity of sound of each measurement system for qualitatively improving the measurement results. The prerequisite for determining the mean velocity of sound propagation is the exact measurement of the distance of the geophones G1, G2, G3 from one another with the aid of remote measuring methods and based on sound or ultrasound. <IMAGE>

Title: Process for separating off ammonia from exhaust air or waste water
Inventor: BORRIES DIETRICH VON DR
IPC: B01D53/84
Filed: 1986-10-22
Abstract: Separating off ammonia from exhaust air, or from gases stripped from waste water (effluent), by means of nitrifying bacteria and the reactors necessary for this are described in the process. In accordance with this, the nitrifying bacteria such as Nitrosomonas europaea and Nitrobacter winogradskyi, are ignited on limestone in the moistened, oxygen-rich air stream or gas stream, in which case they oxidise the ammonia to form nitric acid which is neutralised by the limestone to form nitrates. The carbon dioxide released is at least partially utilised as a carbon source for the growth of the microorganisms. The nitrates formed are separated off by wet or dry means with the reactor devices described and are isolated alone or together with unreacted limestone and used as fertiliser.

Title: Method and device for ionising the sample substance which is contained in a quistor
Inventor: FRANZEN JOCHEN DR
IPC: H01J49/10
Filed: 1987-01-08
Abstract: The resolution capability of a quistor mass spectrometer is limited by dispersion which occurs as a consequence of spatial and temporal expansion during ionisation. The invention is intended to improve the resolution capability of a quistor mass spectrometer. According to the invention, the sample substance is supplied in the form of a supersonic molecular jet (10) to a quistor (1), which jet has a very small diameter and in which the particle density is relatively high. A laser beam (23) is focused on this molecular jet (10). The molecular jet (10) and laser beam (23) have a diameter of only approximately 0.5 mm and 0.1 mm respectively at the penetration point (26). The duration of the laser pulse is only approximately 5 ns. In this way, the ionisation is limited to a very small volume element in the centre of the quistor and to a very short time, with the result that all the ions which are produced are subject to the same initial conditions during their production. <IMAGE>
Patent DE-3701833-A1 (DE)
Title: Method for the optical determination of a catalytic enzyme activity of a sample, and an arrangement for carrying out the method
Inventor: WOLFBEIS OTTO S
IPC: G01N33/58
Filed: 1987-01-23
Abstract: Known methods for the optical determination of the catalytic enzyme activity of a sample, which use enzyme substrates which are cleaved under the influence of the enzyme to be measured and decompose to coloured or fluorescent products, where the increase in colour or fluorescence intensity per unit time is regarded as a measure of the enzymatic activity, have the disadvantage that they are suitable only for optically transparent sample solutions. Measurements on whole blood, in particular in vivo determinations of enzyme activity, are therefore impossible. The method according to the invention avoids these disadvantages by an enzyme substrate being assigned to the end of a light conductor and being contacted with the sample to be measured, and by the change, owing to the enzymatic reaction, in spectral properties of the enzyme substrate or its reaction products per unit time being measured and used for determination of the enzyme activity.

Patent DE-3828270-A1 (DE)
Inventor: SCHOLZ CHRISTIAN DR
IPC: G11B5/31
Filed: 1988-08-19
Abstract: Thin-film magnetic heads have a layered magnetic conductor composed of magnetic core halves (P1, P2 or P3, P4) that overlap each other perpendicularly to the layered structure in the area of a polar tongue (5) with a gap that determines the width of a magnetic gap (6) and at the opposite end in a contact area (4). Windings (3) of a magnetic coil are imbedded in the intermediate zone between the polar tongue and the contact area and enclosed by the magnetic core halves. According to the invention, the magnetic core halves are laterally offset in relation to each other on a plane parallel to the layers, at the same time as the area of their cross-section is enlarged. The proportion of the stray resistance (Rs) in this area is thus increased in comparison to known thin-film magnetic heads.

Title: Steady bearing for a drive shaft of a motor vehicle drive assembly
Inventor: GUTFLEISCH SIEGFRIED DIPL ING
IPC: F16C27/06
Filed: 1988-10-08
Abstract: A steady bearing is described by means of which a drive shaft is to be supported in a support tube of a motor vehicle drive assembly. It is proposed that the said steady bearing be constituted so that it can easily be introduced into the support tube and reliably fixed in this in the assembled position, the intention being to effectively damp residual vibrations originating from the drive shaft, to compensate for bearing tolerances and to suppress oscillation amplitudes. To this end the steady bearing has a roller bearing seated on the drive shaft, the outer race of which bearing, with the insertion of at least one elastomer intermediate ring, is held in a distance ring, brought into engagement with the support tube inner circumferential surface by expansion.
